I really like the app overall which has been divided into 4 main tabs as "Intro", "Map", "Trends" and "Data". The structure is useful, smooth and to the point. It has a concise "Intro" page that explains the data and the goal of the visualization.
The Map part is a bit hard to understand in certain regards. I had difficulty with the year filter appearing as a slider. I thought that it showed information about the crime rate as an aggregate of the interval of years on the slider. However, the map shows information of only one year which appears at the right side of the slider. This can be confusing.
I assumed the size of the points on the map showed the crime rate, but this was not communicated clearly. It can be added as one of the notes on the side panel.
Points on the map have different colors, but it is not clear what these colors mean.
Technical detail to be fixed: years appeared as integers rather than in year format(like "2,005" instead of "2005").
